Optimal lumbar support placement is crucial for maintaining good posture and alleviating back pain.

Ideally, the lumbar support should be positioned at the lower back, specifically at the natural curve of your spine.

This alignment helps to fill the gap between your lower back and the chair, promoting an ergonomic seating posture.

When seated, the support should elevate your lumbar region slightly, allowing your pelvis to tilt forward and your spine to maintain its natural S-curve.

Adjust the height so it fits snugly against your back without causing discomfort.

Regular breaks and stretches can also enhance your overall comfort and well-being. - https://chairpassion.com/blog/where-should-chair-lumbar-support-be/?unique_id_tmre6xf7
